I think People can easily use the P2P platform available on Binance and other centralized exchanges. Why do they need other sites like localbitcoins etc for this purpose?
Also, I think that these sites have been losing business ever since the biggest exchange Binance has launched their P2P platform and that is very secure too.
Not everyone can legally access Binance and not all are fan of centralized exchanges that asks KYC. Besides localbitcoins are famous p2p platform on its prime years not until it asked KYC requirements which started its dooms day.
Nevertheless, the advice of @BitcoinsGreat is very much valid as Binance is a better alternative to Localbitcoins and services like it actually killed the business of Localbitcoins.
Also, if there are countries that ban Binance, and not cryptocurrency generally, such will be so few. I can only read of Singapore and a tiny fractional part of Canada. I didn't dig deeper but I know that Binance offers its service to almost every part of the world. But it is a different ballgame if you want to use DEX, the Ts&Cs must be obeyed including the KYC.
Besides, KYC is not what killed Localbitcoin, it's the too-hot competition in the industry that killed it. I can't have Binance and still think of Localbitcoin, this is obvious in all services you may think of.
